The four United States maps illustrated below show the distribution of people with the surname HEAD within the 50 states for the years 1850, 1880, 1920 and 1990.

The source of this data is the 1850 Census, 1880 Census, 1920 Census, and 1990's phone books.

The color of each state indicates how frequently you will find someone with the HEAD surname in each state. For instance, if a state is colored red, then 1 in 100 people (or more) in that state have the surname. Similarly, yellow means approximately 1 in 500 have the surname, green means 1 in 1000, and blue means 1 in 10,000 (or less).
